ELEVATOR AND CONVEYER.

SPECIFICATION forming part of Letters Patent No. 465,198, dated December15, 1891. Application filed March 5, 1889. Serial No. 301,935- (Nomodel.)

To all whom it may concern.-

Be it known that we, FRANK T. PATTERSON and ALPHONSE FELDPAUOHE, both ofthe city and county of Philadelphia, State of Pennsylvania, haveinvented a new and useful Ele vator and Conveyer, of which the followingis a true and exact description, reference being had to the accompanyingdrawings, which form a part of this specification.

Our invention relates to mechanism for conveying coal or other material,and particularly to a conveyer adapted to receive coal and othermaterial from a railway-car and convey it to a point or points at ahigher level.

The novel features which we claim as of our invention are clearlypointed out in the claims, and will be best understood after anexplanation of the drawings, in which-- Figure 1 is a side elevation ofour device;

Fig. 2, an enlarged transverse section through two conveyer-boxes in theposition they occupy in passing over the .upper guide. Fig. 3 is across-section on the line :20 a: of Fig. 1. Fig. 4 is an enlarged viewof the catch which holds the bottom of theconveyer-boxes in" leadingfrom the road-bed to the conveyer.

B B, 850., represents the framing on which our apparatus is erected.

C is a guide for the conveyer-boxes passing beneath the track A andhopper A, as shown. 0 indicates a sharp rise or elevation in this guide.V

D is a guide situated above guide 0; H, an

endless chain passing, as shown, over guide 0, thence. to and over guideD and back to guide G.

F is a sprocket-wheel which engages and drives the chain II. It may besituated at any convenient point in the guiding-surfaces, but mostconveniently is placed between and at one end of the guides C and D, soas to vir-.

tually form a connection between them, and

the guides C and D should be made tooverilap each other at their otherends, as is shown in Figs. 1 and 5, where D D indicates the downwardlyand inwardly curving end of guide D.

O in Fig. 5 is the guide 0.

G G, &c., are the conveyer-boxes, which are attached to chain H.

'The above-described arrangement of the track, guides, chain,conveyer-boxes, and actupwardly-curving end of v uating device is animportant feature of our invention.

Preferably the guides O and D consist of two tracks, as is indicated inFig. 3, and the chain H made of parallel links united to each other andto adjoining links by axles h, to which axles the conveyor-boxes G aresecured as well as Wheels h, which run on the tracks of the guides.While the guides need-not necessarily consist of or support rails ortracks,

they must at all times present bearing-surfaces substantially equivalentto tracks for the wheels, and we will therefore refer to themhereinafter as tracks. Where the track 0 is horizontal or graduallyinclined, the boxes can be secured to the axles hat both ends, as isillustrated in the case of the supplementary conveyer-boxes at the leftof Fig. 1; but where a steep incline such as 0 exists in track 0 it isnecessary to elevate or depress one end of the box above or below thechain in pass ing over it, and the box is thereforesecured to the axlesh at only one end, and. means, such as hereinafter described,employed-for elevating or depressing the free endof the;

box.

g indicates a hinged bottom to the conveyer-boxes; g lugs extending fromthe edges of the bottom, and g catches pivoted to the sides of the boxesG, with hooked lower ends g adapted to engage the lugs g and hold thebottom g closed.

g are pins to prevent the catches g from turning too far, and g springsto hold them in proper position.

b is a tripping-lug secured on the guide 0 or an adjacent part of theframe, and which, by pressing against the extended upper end of thecatch, causes it to move back and reto fall and dump its load of coal. bis a similar lug secured on or near guide D, which acts to re-engage thecatch with the bottom of the boxes as they pass over guide D.

E, Fig. 1, is a supplemental track arranged at a short distance from andparallel to track 0 in its elevated portion 0', and converging toward itat the top and bottom of the said part 0'. WVhere, as in Fig. 1., thechain H is attached to the back ends of the boxes, this track E shouldlie below track 0, while, if attached to their front ends, thesupplemental track should lie above 0, as is indicated by the chainguideL' in Fig. 5.

Considering, first, the arrangement shown in Fig. 1, it will be noticedthat the boxes G are secured to the axles h at the upper rear corners,while wheels g are secured to their front lower corners. These wheels,running on the supplemental track E, which, in this construction, is aslong or longer than the track 0, over which chain II runs, the distancebetween C and E at all points except at C is such astoenable the boxes Gto run on the wheels h and g with substantially the same effect asthough they were secured to I the modified construction of Fig. 5 theprov chain H at both ends. At 0 the track E diverges from the track 0 atthe top and bottom of the incline to a distance such as will permit thefront ends of the boxes to fall away from the chain to such an extent asto maintain the boxes nearly level, as is shown.

In the modification shown in Fig. 5 the boxes are secured to the chainat the front lower corners, and the supplemental track here serves toelevate the rear ends of the boxes as they pass up the incline 0. Asshown, the supplemental track here consists of an endless chain L,passing over sprocket-wheels F F", one or both of which are driven to aspeed such as will cause chain L to move with the same speed as chainI-I. Hooks Z, on the chain L, engage projecting arms or axle ends 9 onthe back of the boxes, lifting them up and supporting them at a properheight while the boxes are passing over the incline C. It is of courseevident that stationary tracks would have the same effect as chain L ifsimilarly placed above 0'. The arrangement of a supplemental guide ortrack placed in relation to an incline in track 0, so as to maintain theboxes substantially horizontal, is an important feature of ourinvention.

It is advisable to so construct the boxes G that in passing over guideDthey may do so without hanging down from the axles h, to which they areattached. In the construction shown in Fig. 1 this is accomplished bymaking the boxes of such length that their front ends will lie overprojections g of the boxes in front, as is shown in Fig. 2, while injecting rods or axle ends 9 are supported on the track D as the boxespass over it.

Having: now described our invention, what tances to the chain and havingwheels run- I ning on the tracks aforesaid, conveyor-boxes secured atone end to each of said axles and adapted to rest on adjacentconveyor-boxes in passing over track D, a propelling device to actuatethe chain, a supplemental track running substantially paralleland atsome distance away from the incline C of track 0 and substantiallymerging into said track at the top and bottom of the incline, and adevice secured to the free ends of the conveyerboxes, whereby said endsare carried on the supplemental guide or track as the chain passes overthe incline 0', all substantially as specified, and so as to maintainthe boxes practically level in going up the incline.

2. In combination with a track 0, having a steep incline O in it, and atrack D, situated above track 0, an endless chain running over both ofsaid tracks, axles secured at equal distance to the chain and havingwheels running on the tracks aforesaid, conveyer-boxes secured at oneend to each of said axles and adapted to rest on adjacent conveyer-boxesin passing over track 0, a propelling device to actuate the chain, ahinged bottom g in each conveyer-box, a spring-catch g for holding thebottom closed, trips I) b for unlatching and latching the spring-catchat proper points, a supplemental track running substantially paralleland at some distance away from the incline C of track 0 andsubstantially merging into said guide at the top and bottom of theincline, and a device secured to the free ends ofv the conveyor-boxes,whereby said ends are carried on the supplemental track-as the chainpasses over the incline O,

maintain the boxes practically level in going up the incline.

.all substantially as specified, and so as to v 3. In combination with atrackC, having a steep incline C in it, a' track D, situated above track0, a supplemental guide E, situated beneath the track 0 and convergingtoward it at the top and bottom of the incline C, an endless chainpassing over tracks 0 and D and having axles secured to it at equaldistances, wheels secured on said axles so as to run on the tracks 0 andD, conveyorboxes secured at their back upper ends to the axles of theendless chain, wheels secured to the front lower ends of theconveyor-boxes, so as to run on the supplemental track or guide E, andmechanism for driving the endless chain.
